ChatGPT vs Gemini vs Perplexity for Local Search

Short answer: All four engines search the live web before naming a local business, but they lean on different sources. ChatGPT uses third-party search providers plus partner data such as Yelp. Gemini draws on Google Search and Google Maps. Perplexity cites community sites like Reddit heavily. Claude runs its own web search. Consistent facts everywhere help with all four.

This guide sticks to what the companies document and what published studies show. Where a claim is only reported, not confirmed by the company, we say so. Where the evidence is thin, we say that too. Nobody outside these companies knows the exact ranking logic, and nobody can guarantee you a spot.

Where does ChatGPT get local business recommendations?

ChatGPT searches the web when a question needs current information. It pulls results from third-party search providers and from content partners, then writes an answer with citations. For local questions, Yelp is now a confirmed data partner, and independent research suggests the web results closely track Bing.

OpenAI's ChatGPT search help page says search uses third-party search providers and content supplied directly by partners. It also says ChatGPT may share your approximate location, taken from your IP address, with those providers. Its example: "good restaurants near me" can be rewritten into a search like "top restaurants San Francisco." So a local answer usually begins as an ordinary city-plus-category search.

OpenAI has not published how much of that search comes from Bing. The best public evidence is a Seer Interactive study (February 2025, 500+ citations across 100 queries). It found that 87% of ChatGPT search citations matched Bing's top organic results, against 56% for Google. That is a small, early sample. Treat it as a strong hint, not a confirmed fact.

The Yelp link is confirmed. In an August 2026 announcement, Yelp described an existing content integration that shows its reviews, ratings, photos and business details inside ChatGPT, and added reservations and waitlists on top.

• Crawlers: OpenAI's bot documentation says OAI-SearchBot surfaces sites in ChatGPT search results, ChatGPT-User visits pages for user actions, and GPTBot is for model training. If you block OAI-SearchBot, your site won't show up in ChatGPT search answers.
• Bing: Claim and verify your listing in Bing Places and check that Bing indexes your site. Given the Seer finding, this is cheap insurance.
• Yelp: For restaurants and home services especially, a complete, well-reviewed Yelp page now feeds ChatGPT directly.

How does Gemini pick local businesses?

Gemini leans on Google's own data. Google says the Gemini app uses public information from Google Maps to find businesses and to give their ratings, hours and websites. Google's AI Overviews and AI Mode build answers from pages in the Google Search index. Your Google Business Profile and your Google rankings are the foundation here.

Google's Gemini Apps help page says Gemini uses "public information from Google Maps" to find places such as businesses, stores and restaurants, and to return addresses, descriptions, websites, ratings and opening hours. That Maps data is largely what you control through your Google Business Profile. Google also offers developers grounding with Google Maps, which pulls in places, reviews and hours, so apps built on Gemini can draw on the same data.

For AI Overviews and AI Mode, Google's AI features documentation says a page must be indexed and eligible to appear in Search with a snippet, with no extra technical requirements. It also says both features may use "query fan-out," running several related searches across subtopics and data sources. Google does not publish how Business Profile signals are weighted inside those answers, so ignore anyone who claims to know the exact formula.

• Google Business Profile: Get the categories, hours, services, photos and website link right. This is the Maps data Gemini reads.
• Reviews on Google: Ratings appear in the Maps data Gemini returns, so recent, genuine reviews matter.
• Crawler: Googlebot covers Search, including AI features. Google points to Google-Extended for training and grounding in its other AI systems, not for Search eligibility.

Why does Perplexity cite Reddit so often?

Perplexity's top sources lean heavily toward community discussion. In Profound's large citation study, Reddit made up 46.7% of citations among Perplexity's ten most-cited sources, the highest share any single domain had on any platform. Perplexity hasn't explained why, so the reason itself isn't known.

The Profound study covered 680 million citations from August 2024 to June 2025. Read the 46.7% carefully. It is Reddit's share within Perplexity's top ten sources, not its share of every citation. The same analysis put Yelp (5.8%) and Tripadvisor (4.1%) in Perplexity's top ten. That matters for restaurants and home services. For comparison, Wikipedia led ChatGPT's top ten at 47.9%, and Reddit held 21.0% of Google AI Overviews' top ten.

On crawlers, Perplexity's bot documentation says PerplexityBot surfaces and links websites in Perplexity search results and is not used for training foundation models. Perplexity-User fetches pages when a user asks a question, and Perplexity says it generally ignores robots.txt because a person started the request.

• Allow PerplexityBot or your site can't be surfaced in its results.
• Be discussed honestly on Reddit in your local and trade subreddits. Answer questions, don't spam links. Our Reddit and AI search guide covers how.
• Keep Yelp and Tripadvisor current if you're in food, hospitality or home services.

Does Claude recommend local businesses?

Yes, when web search is on. Anthropic says Claude may use your approximate location, taken from your IP address, for localized requests, and every search answer includes citations. Anthropic doesn't document a local data partner like Yelp for Claude, so the public evidence on its local sources is the thinnest of the four.

Anthropic's web search help page confirms the location behaviour and says image search is powered by Bing. It doesn't name the provider for text search. In March 2025, Anthropic added Brave Search to its subprocessor list, and independent testing found Claude's cited results matched Brave's. That points to Brave as a likely backend, but Anthropic's own search docs don't say so.

Anthropic's crawler page lists three bots: ClaudeBot collects content that may be used for training, Claude-SearchBot improves search result quality, and Claude-User fetches pages when a user asks Claude a question.

• Allow Claude-SearchBot and Claude-User. Blocking ClaudeBot only affects training.
• Check your visibility in Brave Search. It costs nothing, and the evidence points that way.
• Make your own site quotable, with clear services, service area and prices, because without a known local data partner your site and third-party pages do most of the work.

How do the four engines compare side by side?

The four differ most in where their live web results come from and which local data they lean on, which is why a business that one engine names confidently can be missing from another. The table below sets out the retrieval source, the local signals and the one priority that matters most for each.

What works across all four?

Every engine starts with a live search, reads what it finds and names businesses that several sources back up. The winning move is the same everywhere: let the crawlers in, keep your facts identical everywhere, and earn real reviews and mentions on the platforms each engine reads most.

The key takeaway is that there's no single "AI ranking." There are four retrieval pipelines with different favourite sources. Google data drives Gemini, Yelp and probably Bing feed ChatGPT, Reddit carries unusual weight in Perplexity, and Claude relies on its own web search with no documented local partner. A dentist who only polishes a Google profile can win Gemini and still be missing from the other three.

• Check robots.txt for all the search and user bots in the table. Our AI crawler robots.txt guide has copy-paste rules.
• Use the same name, address, phone, hours and services on your site, Google, Bing, Yelp and trade directories.
• Put the answer on your site in plain words: what you do, where, for whom, and roughly what it costs.
• Earn reviews steadily on Google and on Yelp or your trade's main review site, and reply to them.
• Re-check regularly. Answers change from run to run (see why AI answers change every time), so one screenshot tells you little.

What else do people ask about the different AI engines?

Which engine should a local business prioritise?

Whichever your customers use, but if you must pick one, Google surfaces reach the most people through AI Overviews and Gemini, and the work overlaps heavily with what the others need.

Do I need separate content for each engine?

No. The content is the same; what differs is crawler access, indexing and which third-party sources each engine leans on.

Why does the same question get different businesses on each engine?

Because each retrieves from a different source mix and summarises what it finds. Strength in one engine does not carry over, which is why checking all four is worth the few minutes.

Does Claude recommend local businesses at all?

It can when it retrieves live results, but it is generally more cautious about naming specific local businesses than Perplexity or Gemini, and leans on clearly written sources.

What should a local business do this week?

Start by finding out what each engine says today. Ask all four the question a real customer would ask, like "best emergency plumber in Leeds", and see who each one names. Then fix the gaps for whichever engine leaves you out.

• Day 1: Run the free 60-second Alphaa check. It asks ChatGPT, Gemini, Claude and Perplexity the same customer question, shows who each one named, and runs 23 checks on what AI can read on your site.
• Day 2: Fix any blocked crawlers and mismatched listing details it finds.
• Days 3–5: Claim or complete Bing Places, Yelp and your Google Business Profile, then ask recent happy customers for reviews.

If you'd rather have it handled, Alphaa is an AI agent that keeps working to get local businesses recommended by all four engines. It starts at $99/month, month to month. There's no free trial, and no honest provider can promise rankings. You'll see what changes, engine by engine.
